Is there any way to save the state of the logs in Logstash JDBC input plugin?

For example, for file input plugin, there is [`sincedb_path`](https://www.elastic.co/guide/en/logstash/current/plugins-inputs-file.html#plugins-inputs-file-sincedb_path) which remembers where it left off from reading the logs.

Yes, the jdbc input can persist [state](https://www.elastic.co/guide/en/logstash/current/plugins-inputs-jdbc.html#_state).

I'm not sure what value to include for sql\_last\_value as JDBC state. Coud you please clarify this?

Look at the documentation for the tracking\_column, tracking\_column\_type and use\_column\_value on the jdbc input. If you search in [this forum](https://discuss.elastic.co/search?q=sql_last_value%20category%3A14%20use_tracking_column) you will find many examples of people using them.
